Image-Segmentation-Method
本文主要研究基于水平集方法的活动轮廓模型图像分割，在回顾活动轮廓模
型发展的基础上，介绍了曲线演化理论及其水平集方法，证明了水平集方法可以
有稳定的数值实现方式且其处理拓扑变化的自然性，进一步引出了变分水平集方
法。
本文介绍了两种不同的几何活动轮廓模型：基于梯度信息的李纯明模型以及
基于区域信息的 Chan-Vese 模型（C-V 模型）。在分析上述两模型的优缺点上，提
出了一种改进的 C-V 模型，改进模型引入了距离约束项，同时对基于区域的外部
能量项进行了改进，使得水平集函数重新初始化寓于模型的演化之中，分割结果
对参数的依赖性减小。
(This paper mainly study image segmentation of active contour model based on
level set. After reviewing the development of the active contour model, curve evolution
and level set method are presented, then we proved that the level set method has a stable
numerical realization and can describe the topology change of the contour naturally, in
addition we introduce level set of variational method.
We introduce two different GAC models in this paper: Li Chunming model which
is based on gradient information and Chan-Vese model （C-V model） which is based
on region information. Based on the drawbacks and advantages of these two models, we
improve the C-V model by adding penalizing energy term of signed distance function,
at the same time, mending the external energy term which based on region information,
then the re-initialization of the level set can accomplish in the model evolution, and the
degree of the segmentation result depend on the parameters decline.

首先生成如下形式的图片：图中的白条为7象素宽，210象素高，白条间的宽度为17象素。
应用多种滤波器进行处理：算术均值，几何均值，谐波均值，逆谐波均值，中值滤波，中点滤波，最大值、最小值滤波等。注意，需改变模板大小。详细比较上述的结果，并分析原因。
(First generation following form images: figure IOUs 7 pixels wide, 210 pixels high, the width is 17 pixels between IOUs. Using a variety of filters for processing: the arithmetic mean, geometric mean, harmonic mean, inverse harmonic mean, median filtering, filtering midpoint, maximum, minimum filtering. Note that the need to change the template size. A detailed comparison of these results and analyze the reasons.)

程序为读取图片并对图片进行边缘检测，先采用高斯滤波进行去噪，然后通过求梯度运算检测，非极大值抑制边缘检测，双阈值检测这三种方法，分别对图片进行边缘测，并对边缘检测后显示的图片进行对比。此程序对边缘检测有很大的参考价值。(Program to read the image and image edge detection, Gaussian filter to remove noises, and then detected by calculating the gradient operation, the non-maxima suppression edge detection, dual-threshold detection of these three methods, namely the picture edge test, and the rear edge detection to display image comparison. This program is great for edge detection reference value.)
